TELEPHONE-TRANSMITTER.

SPECIFICATION forming part of Letters Patent No. 469,782, dated March 1, 1892. Application filed June 12 1891. Serial No. 396,045. (No model.) Patented in England July 12, 1889, No. 11,215-

To all whom it may concern.-

Be it known that I, JOSEPH CUTHBERT GOULDING, a subject of the Queen of England, residing at Cardiff, in the Kingdom of England, have invented certain new and useful Improvements in or appertaining to Telephone-Transmitters, (forwhich I have secured Letters Patent in Great, Britain, No. 11,215, dated July 12, 1889,) of which the following is a specification.

This invention has forits object a transmitter so arranged that it can be placed at any desired height by the person temporarily using it, and thus a man, tall or short, can either sit, stand, or, if necessary, even lie down while transmitting a message.

In carrying out my invention I arrange the wires with a considerable amount of play and place the transmitter on a carriage, of wood orothermaterial,travelingverticallyin guides or rails on or in proximity to the wall. The telephone can be made to serve, when re quired, as many floors as there may be in the building in which it is used, all that is required to adapt it for this purpose being a sufficient lengthening of the vertical guides and the terminal wires.

The invention is best described by aid of the accompanying drawings, in which- Figure 1 is a side elevation of the uprightguides fixed in proximity to the wall and of the telephonic apparatus mounted on the carriage adapted to slide vertically between said uprights; Fig. 2, an elevation, viewed from the back, of the uprights, sliding carriage, slack wires, and device for clamping the carriage in any required position in its vertical path; Fig. 3, a front elevation of the clamping device shown in Fig. 2, but drawn on a larger scale than said figure; Fig. 1, a side elevation of a portion of said clamping device.

In the drawings, A A are hollow uprights, preferably of metal; 0, the carriage, having guides e and d and capable of sliding vertically between said uprights and on which the telephonic apparatus B is mounted.

D is a wall or partition to which the uprights aforesaid are fixed by brackets d or their equivalents, so as not to lie against the wall, thus overcoming the vibration from that source and preventing noises or conversation in an adjoining apartment (which would be audible if the telephone were placed in contact with the wall) from disturbing the operator while he is at work.

E E are pulleys over which pass cords e 6, attached at one end to the carriage O and at the other to counter-weights e 6 the combined weights of which are approximately equal to the weight of the carriage aforesaid and the telephonic apparatus attached thereto. The telephonic, apparatus can thus be raised or lowered, as desired, without undue exertion to suit the height or convenience of each individual operator. The guides e e aforesaid are permanently fixed to the carriage C in proximity to its lower end. The other guides cl cl are designed to slide horizontally and clamp the carriage C at any height in its vertical path.

F is a disk axially mounted on the carriage O and adapted to be rotated by the handle I).

ff are eccentric grooves or slots in said disk, which receive the studs h on the clampingguides cl, Figs. 3 and at. When the handle I) is rotated in one direction, the eccentric grooves in the disk aforesaid simultaneously thrust the clamps cl d outward against the uprights A and so bind the carriage O that it cannot be moved accidentally or otherwise until the handle I) is turned in the opposite direction, when the clamps d are drawn back clear of the uprights and leave the carriage free to be moved in its vertical path.

To the transom G are attached two terminals t c. To these and to the telephonic apparatus on the carriage G are connected the flexible wires g, which are of such a length as to allow of the board being moved from the top to the bottom of the uprights. Another arrangement is to provide the carriage with a handle and a stop,which,if desired, may be connected. together. The handle is used for raising or lowering the carriage when the 'stop is withdrawn. The stop can fit into a series of holes perforated-closely together in one or both of the rails, or it can rest in the teeth of a rack placed alongside the rail or projecting from it, or it can be made simply to act by friction. When the weight of the transmitter comes on it, the friction device wedges itself against the rails and makes the transmitter immovable. By lifting up the wedging device, however, by the handle that guides the transmitter or by other mechanism or by simply withdrawing it the transmitter can be raised and lowered as desired. It will be obvious, also, that an ordinary bolt worked by a handle either in a reciprocating manner or radially can be used to lock theinstrnment in place when it has been put to the desired height. A cushion or base H is placed at the bottom of the vertical uprights, so that the transmitter and its carriageOshall be unable to fall out of them at the bottom, and at the top the cross-piece or transom G aforesaid is placed, so that no unauthorized person can withdraw the transmitter carriage. It desired, the cords ve 6' may be utilized as conducting-wires for the electric current in addition to their use as snspenders.

Having now particularlydescribed and ascertained the nature of my said invention and in What manner the same is to be per formed, I declare that what- I claim is 1. The combination of two uprights with the carriage C, carrying the telephone applt ances, adapted to slide between said uprights, and a locking device for locking the carriage against motion,consisting of a revoluble disk provided with segmental grooves f and guidearms adapted to slide to and from the uprights, said guide-arms having friction blocks or shoes at one end in contact with the uprights and at the other a pin extending into the slots in the disk, substantially asdescribed, for the purpose set forth.

2. The combination, with the tubular uprights A,of a weight contained in each upright, the carriage 0, connected with the weights by cords e running over sheaves E at the upper end of said uprights, said carriage (J carrying the telephone appliances, the revoluble disk F, connected with said carriage and having two segmental grooves f, and the guide-arms d d, having a friction block or shoe at one end incontact with the uprights and a pin h at the other extending into the grooves of the disk, said guide-arms being adapted to slide over the carriage to and from the uprights, substantiallyas and for the 'purposesetforth.

In testimony that I claim the feregoingas my invention I have signed my name, in presence of two witnesses, this 23d day of li/Iay,-

JOSEPH CUTHBERI GOULDING.
